The Oxbow Preserve was created in 2004 by Union Pacific Homes as mitigation for a development in the City of Lathrop. This 30-acre Preserve was established to protect the federally endangered riparian brush rabbit (Sylvilagus bachmani riparius). The Center for Natural Lands Management (CNLM) took ownership of this Preserve in 2004.
This Preserve is comprised of mixed-age riparian forest located adjacent to the San Joaquin River. Valley oaks (Quercus lobata), cottonwoods (Populus fremontii), willows (Salix spp.), elderberry (Sambucas nigra caerulea), and wild rose (Rosa californica) are common within the Preserve. The Preserve provides critical habitat for the riparian brush rabbit and is one of only a few remaining sites within the San Joaquin watershed that have populations of this endangered species. The Preserve also provides habitat for Valley Elderberry Longhorn Beetle (Desmocerus californicus dimorphus) and the state threatened Swainson’s hawk (Buteo swainsoni). More than 75 species of birds have been identified within the Preserve.
CNLM primary goal is to protect the riparian brush rabbit population and its native habitat. CNLM monitors the Preserve’s conditions including addressing trespass violations, monitoring exotic predators (e.g. feral cats), changes/trends in vegetation and vandalism, removing trash and debris, repairing gates, fences, and signs, and controlling exotic invasive plants. In addition, our activities include coordinating access to the Preserve for outside researchers and monitoring Riparian brush rabbit populations through the use of remote motion activated cameras.
Due to the vulnerability of the species and habitats that exist on this preserve, it is not open to the public.
